The trapping of trace elements by minerals in soils and oceanic sediments is an important process. Krauskopf (1956) showed that adsorption of trace elements on mineral surfaces controls the trace-element concentration of seawater. Here we show how this concept may be extended to major elements such as Si and Al. Most of these elements ( e.g., Fe, Si, P, and N) are either essential nutrients or structural materials for organisms in the surface ocean and thus have a considerable environmental interest (e.g., Baker et al., 2010).

River and glacier transport dominate the supply of elements...
